Hi,
seems like libc version on 4.6 branch are binary incompatible. Doing a
simple malloc fails, when compiled on a newer version. Linking with
-static makes it work. Programs compiled on older version, work on the
newer one:
ralf@monster:~$ cat t.c
#include <stdlib.h>
#include <stdio.h>
int main()
{
if (!malloc(100)) {
perror("malloc failed");
}
return 0;
}
ralf@monster:~$ gcc -v; uname -a
Using builtin specs.
